摘要

Abstract

Eleven copper(I) halide complexes [CuX(CNR)₃] (X = Cl, Br; R = C₆H₃-2,6-Cl₂, C₆H₃-2-Cl-6-Me, C₆H₃-2,6-Br₂, C₆H₃-2-Br-6-Me; X = I, R = C₆H₃-2,6-Cl₂, C₆H₃-2-Cl-6-Me, C₆H₃-2-Br-6-Me) bearing halogen-functionalized aromatic isocyanide ligands were synthesized. The compounds were characterized by atomic emission spectroscopy (Cu), IR, ¹H NMR spectroscopy and high-resolution mass spectrometry. The structure of nine compounds was determined by X-ray diffraction. Structural studies allow to reveal that the supramolecular structure of the complexes is based on weak C–H···X (X = Cl, Br, I) interactions and π-stacking of the aromatic rings of isocyanide ligands.
